Abstract

A method and system are provided which, in a program recording apparatus which performs recording of television programs, enable even those users who are inexperienced in operating machines to simply, directly and flexibly perform a program recording reservation operation and a recorded program viewing operation. An association is first made between position information on a paper or sheet with program information, and the user inputs a program specification using a program schedule and a digital pen. The information input by the pen is converted to program information, and a program recording reservation is made. If the recorded program list is printed out or various content lists are used, program playback and content management can be performed with greater ease.

Description

CLAIM OF PRIORITY

The present application claims priority from Japanese patent application P2005-11039 filed on Jan. 19, 2005, the content of which is hereby incorporated by reference into this application.

BACKGROUND OF THE INVENTION

The present invention relates to a recording apparatus for recording a broadcasting signal of a television program to a recording medium, and in particular, a recording apparatus and recording method which designate a program to be reserved for recording and to be viewed by using a digital pen.
Program recording apparatus for recording a television program on a hard disk, DVD (Digital Versatile Disk) or videotape are widely used. To specify recording of a specific program beforehand, it is required to make a recording reservation. Various means are used to make a complicated recording reservation simpler.
One of these methods, disclosed in U.S. Pat. No. 5,974,222 B2, is to use a number sequence known as a G code. The G code replaces the four elements of recording date, channel, program start time and program length by a number of up to eight digits, and permits recording reservation to be performed. When the user inputs this number sequence by remote control or other means and it is transmitted to the recording apparatus, it is decoded in the recording apparatus, and the desired program is reserved.
Another example of a technique that simplifies recording reservation has been put to practical use recently by the EPG (Electric Program Guide), as disclosed in JP 2,838,892 B2 and JP H1-307944 A1. EPG is a system that displays a program schedule on a television screen. Program schedule data may be sent out using the gaps between radio waves and received by a special terminal, or a network terminal connected to the television is used. A videocassette recorder which can make a recording reservation based on the EPG data has also been put into practical use.
Due to multi-tuner installations which can record plural stations simultaneously, and increased capacities of recording media for recording programs, it is now possible to record many programs simultaneously. Consequently, it is now becoming increasingly popular, instead of selecting a program which it is desired to record, to record a large number of programs by first inputting keywords and other conditions, and then select the desired program later from among these. In other words, instead of watching television at the program broadcast time as before, the user can now freely decide how to watch programs and in what sequence.
In WO 01/71473A1, a pen type input apparatus known as a digital pen is described which has come into practical use. This acquires the trace of a pen nib electronically and inputs it to an electronic computer, such as the “Anoto pen” developed by the Swedish company Anoto. A digital pen has the advantage that it can easily be used even by a user unfamiliar with the use of a keyboard or mouse, and it is expected to be useful when making applications to electronic governments or for other purposes.

SUMMARY OF THE INVENTION

In the related art method of using a G code to reserve recordings, the user needs to input a line of up to eight digits manually by an input means, such as remote control. It is very troublesome to input a seemingly meaningless sequence of numbers so that they can be converted to program data, input errors occur frequently and often lead to recording reservation errors. In a recording reservation method using EPG, a program schedule is displayed on a screen of a television (or, a personal computer or cellular phone connected to a network) and a desired program is selected from the schedule. Although the program schedule display on the screen is easy to search, there is however a limit to viewing a screen display, and it is difficult to operate successfully by a user who is inexperienced in operating machines.
Moreover, along with the progress made in recording apparatus described above, it is difficult to search desired programs from a large number of recorded programs, and when too many have been recorded, to know which ones are desired.
It is therefore an object of the invention to provide a method and system which permit the scheduling of program recording and the viewing of recorded programs to be performed simply, intuitively and flexibly even by a user who is inexperienced in operating machines.
Television program guides found in newspapers and magazines are widely employed to give information about television programs. These television program guides on paper media are convenient and portable, and since they permit the user to view and consult information at any time, in any location and in any occupation, they are extremely useful.
The aforesaid digital pen makes it possible, while retaining the advantages of these paper media, to provide a means of simply, intuitively and flexibly scheduling recording and viewing programs.
Specifically, an association is first established between a position on paper (or sheet, hereafter “paper”) and program information, and correspondence information is stored on a server via a recording apparatus or network. The user inputs a program specification using this paper with associations and a digital pen. Information about the trace of the pen is converted into program information according to the previously established associations, thus completing specification of the programs it is designed to record or view. By arranging the program sequence specified by the pen to be the desired viewing sequence, the user can view programs in a preferred sequence regardless of the sequence in which they were broadcast. Further, by first making an association between the pattern of motion of the pen and the recording/viewing method, it is also possible to specify the recording method, and the playback sequence/playback speed when the programs are viewed.
These operations, in addition to the viewing of programs, may also be used as tools for managing various content, i.e., not only recorded television programs, but also music files and image/movie data acquired from digital cameras or video cameras, content data stored on media such as DVD/video, CD and the like, or streaming data received from outside via a network. An association is established between the content and position information on paper, and the playback or management of this content is performed using a digital pen.
According to the present invention, there are therefore provided a method and system which permit information to be viewed and consulted in a convenient and portable format at any time, in any location and in any occupation, and which permit the simple, intuitive and flexible scheduling of program recording, viewing of recorded programs and management of various contents.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 shows the flow of a system outline implemented by the present invention and rough processing. A user 1 checks a program schedule 40 related to program information by using a digital pen 10, and selects a program to be recorded (101). The relation between the position of the program schedule 40 specified by the pen 10 and program information are stored in a memory beforehand as program information conversion data 50. The trace of the pen used by the user 1, and pen input information such as the nib pressure and input time, are transmitted (102), analyzed (103), and converted to corresponding program information using the program information conversion data 50 (104). This information is used for reserving recordings and specifying the viewing method in a program recording apparatus 20 (105). A display unit 30 is used to display images recorded by reservation according to the aforesaid specification procedure, or display movies selected for viewing by the aforesaid specification procedure.
Here, referring to FIG. 2, as one example of the digital pen 10 used in this embodiment of the invention, the digital pen 10 disclosed in WO 01/71473A1 Patent Document 3 will be described.
The digital pen 10 is used with a form 60 that has a mark for detecting a position corresponding to this method. The digital pen 10 comprises a communication module 11, memory 12, processor 13, camera 14, battery 15 and nib pressure sensor 16. Since the digital pen 10 also has an ordinary nib with ink, when something is filled in on paper with this digital pen 10, the information visually remains on the paper.
In the digital pen 10, the image of a pattern for detecting position which is printed on the paper is acquired by the camera 14. Looking at the form 60 in more detail (61), small dots 62 are scattered and printed non-uniformly on the form. These dots are all printed offset to the top, bottom, left or right at a certain distance from the intersections of virtual grid lines 63. Taking a combination of these dots (for example, an area of 6×6), a combination of values of the top, bottom, left and right offsets of these 36 dots gives absolute position information over an expansive plane region.
Positions in a space formed by a combination of offsets can be specified by acquiring an image within a range including the aforesaid plural dot pattern at a constant time interval by the camera 14 with which the digital pen 10 is provided. Details of this principle are clarified by WO00/73983 A1.
The digital pen 10 has a communication interface 11 such as Bluetooth or Universal Serial Bus (USB), and information such as pen the trace and nib pressure is transmitted to a forwarding apparatus 64 such as a personal computer or cellular phone.
The forwarding apparatus 64 communicates with a Paper Look-up Service (PLS) server 65 via a network 5 (e.g., the Internet). When the use of the digital pen 10 starts, the PLS server is associated to the input pen, paper and application. The PLS server receives a pen ID and paper ID, and authenticates the pen. Subsequently, matching is achieved with an application corresponding to the paper, and the URL of an application server 612 is returned.
Due to this processing, an application corresponding to the filled form is launched, and pen input data is correctly sent to the corresponding server. The PLS can also specify coordinates on paper from the dot pattern acquired by the camera 14, and output specified coordinates for the purpose of the application.
The aforesaid coordinate position on paper is specified by the PLS server which is a exclusive server that manages the dot pattern. Further, if information required to specify the paper ID, pen ID, input coordinates and the application is stored beforehand in another apparatus such as a server of a program information center (application server) or a video recorder, the digital pen 10 can be used for the application without accessing the PLS server every time.
There is an advantage that if this digital pen 10 is applied to the present invention, a program printed on the program schedule can be freely specified by the trace that the user traces with the pen. An embodiment using this digital pen 10 will now be described. It will of course be understood that the invention is not limited to this type of digital pen 10, and another input means may be used provided that a position on paper can be specified by user input, and a program can be specified corresponding to the specified position.
Next, referring to FIG. 3 and FIG. 4, a method of specifying a program by a pen in the system and service of this embodiment will be described.
FIG. 3 shows an example of methods of (commands for) selecting a program from a program schedule 70.
Method (A) is a method wherein, check boxes 71 are printed for each program, and check marks 72 are respectively made in check boxes for the programs it is desired to select. According to method (A), the program to be selected can be selected surely. However, when the program guide is printed, the check boxes must also be printed and the previous layout of the program schedule on paper must be changed.
Method (B) is a method wherein a large check mark 73 is made on program information to be selected. According to method (B), the program can be specified relatively easily. However, there is a problem that when there are many programs of short duration arranged crowdedly, it is difficult to ascertain which program was specified.
Method (C) is a method wherein a program column of the program information to be selected frame is enclosed by a line 74. Method (C) has the advantage that it is easy to ascertain which program was selected, and programs in the same time zone and on the same channel can be specified together (FIG. 4).
Method (D) is a method of marking a circle 75 on the program information to be selected. According to method (D), the user can select the program naturally. This is convenient when specifying plural programs together.
Method (E) is a method of marking an arrow 76 in the time zone of the selected program. This is convenient when selecting consecutive programs together, and the viewing sequence of plural programs is specified (FIG. 4).
To cancel a program selection, the program selection is cancelled by marking a large cross 82 with the pen to cancel the original program selection 75.
FIG. 4 shows an example of a method of selecting plural programs from the program schedule 70.
Method (F) is a method of enclosing program information to be selected by a circle 77. According to method (F), programs in a specific time zone can be specified together. Likewise, programs on the same channel can be specified one after the other.
Method (G) is a method whereby, in addition to reserving a recording, the viewing method is specified. For example, if arrows are marked in the sequence 78, 79, 80, 81 on one program schedule, program playback and the viewing sequence can be specified by the sequence of the arrows.
Further, by making an association between a command specifying the recording method and the viewing method with a pen gesture in advance, not only program recording but also the viewing method can be set according to the user's preferences. For example, the spiral arrow 80 may define fast forward, and the arrow 81 may define recording to the end even though a program was extended.
Next, referring to FIG. 5 and FIG. 6, examples of the format of the program information conversion data 50 in FIG. 1, the means for creating data and the means for acquiring program information, will be described
FIG. 5 is one example of a method of creating data for program information conversion. Program data 57 (e.g., EPG data) acquired via a network 5 is a set of individual program information 310. The individual program information 310 includes a program ID 311, channel 312, start time and date 313, end time and date 314 and additional program information 315. The additional program information 315 is information such as the title, genre and performer, etc.
The program information 310 is arranged on the program schedule according to the layout 241. Alternatively, it may be laid out beforehand like a current television program guide. Arranged program arrangement information 320 has a paper ID 321 to distinguish the issue number and page of the program guide, and individual program information 323, 324 is disposed on corresponding X axis and Y axis (322).
From the program layout information, information is acquired as to which program is located at which position on the program schedule and with which paper ID (paper ID and coordinate data set 325) (242), and stored in a database together with the original program information (243).
Information 330, which is a combination of the original program information, paper ID 316 and corner position 317, is stored as the program information conversion data 50. If plural types of command can be used by the pen input shown in FIG. 3 and FIG. 4, data 334 showing associations between pen gestures and commands may be stored beforehand, and used for program specification processing described later. The association data comprising the gestures and commands may be updated by learning the user's habits.
Next, referring to FIG. 6, an example of a method for converting pen input data into program information using the created program information conversion data, will be described.
The pen data input by the methods shown in FIG. 3 and FIG. 4 is stroke data wherein the paper ID 326, pen position 327 and nib pressure 328 arranged in a time series, are collated in a time sequence.
A database is searched by comparing with the coordinates of the program data 320 of the program information conversion data 50 based on the obtained coordinates information (253), and corresponding program information is acquired (254). For example, when pen input data 74 enclosed by a square is obtained for the program frame 324, coordinate information for the region enclosed by the pen (e.g., X axis minimum value: Xmin, X axis maximum value: Xmax, X axis center value: Xcenter, Y axis minimum value: Ymin, Y axis maximum value: Ymax, Y axis center value: Ycenter) 332 is compared with coordinate information for the program frame (upper left coordinates: (Xs,Ys), upper right coordinates: (Xe,Ye)) 333. The data contained within the enclosed region is then searched.
When the pen input data is analyzed, gestures are recognized together with the coordinates (252). A viewing method 318 (e.g., playback speed setting and extended processing, etc.) corresponding to a rule 334 of a predetermined gesture, can be specified. Program data (program ID, channel, start time and date, end time and date, additional program information and recording method (or, viewing method)) 331 converted from the pen input data is then transmitted in a time series to the program recording apparatus.

FIRST EMBODIMENT

Hereafter, referring to FIG. 7 to FIG. 11, a first embodiment of the present invention will now be described.
FIG. 7 is a system configuration diagram of the first embodiment.
The system of the first embodiment comprises a digital pen 10, a video recorder 21 corresponding to this system, an video display apparatus 30 such as a television or monitor, a television program guide 41 corresponding to this system, a server 51 for providing the whole service and program information conversion data 50.
The video recorder 21 is a program recording apparatus for storing program data on media such as a hard disk drive or DVD. The server 51 and program information conversion data 50 in a program information center 4.
Next, the processing of the service provided by the first embodiment will be described.
(A) In the program information center 4, television program guide information is first printed on a form corresponding to the digital pen 10 used with this system, and associations are made between coordinates and program information on each page of the television program guide 41. The association information is stored in the program information server 51 as program information conversion data 50 (111).
(B) A printed program guide is distributed (112).
(C) The user 1 obtains the television program guide 41, and peruses the obtained television program guide 41 at his home 2 or another location 3. When he finds a program he desires to record, he makes a mark in the relevant program column using the digital pen 10. The program is selected by this mark with the digital pen 10 (113). An example of the program selection method is as described above in FIG. 3 and FIG. 4.
(D) In the program selection operation, data acquired by the digital pen is stored by the digital pen 10, and forwarded to the video recorder 21 corresponding to this system with a suitable timing (114). The communication method used at this time is a wireless communication method such as Bluetooth, or a wired communication method such as USB connected by a wire or the like.
(E) The video recorder 21 accesses the server 51 of the program information center 4 via the network 5, and transmits the information acquired by the digital pen 10 (115).
(F) The server 51 analyzes the information acquired by the digital pen 10 (116), looks up the program information conversion data 50, and converts the information acquired by the digital pen 10 to corresponding program information. Also, if required, pen gesture/command correspondence data 334 is looked up, and pen gestures are converted to commands.
(G) The converted program information is transmitted to the video recorder 21 (117).
(H) The video recorder 21 completes the recording reservation based on the obtained program information (118).
Due to this processing, the user 1 can complete the reservation of a desired program recording simply by selecting the program from the printed program guide and transmitting it to the video recorder. The reservation method of this embodiment differs from the reservation method using a G code since it can select a program by a natural operation. Further, the user can select and reserve plural programs in which he is interested at the same time.
FIG. 8 is the configuration of the video recorder used with this system.
The video recorder 21 comprises a recording medium including a hard disk drive 22, DVD disk 23, DVD disk drive 24, control unit 25, tuner 26, video display unit 27 and communication interface 28.
The hard disk drive 22 stores video, audio and control data for reserving recordings or selecting programs to view. The tuner 26 receives a video signal stored on the storage medium. The video display unit 27 controls an video display apparatus such as a television or monitor. The communication interface 28 is connected with an input device such as the digital pen 10 and with the server 51.
The video display unit may be integrated with the video recorder 21, or it may be another apparatus.
FIG. 9 shows the configuration of the server in the first embodiment.
The connection between the video recorder 21 and server 51 is established by the PLS server 65 described in FIG. 2, and information acquired by the digital pen 10 is sent to the server 51. The server 51 comprises a processing module 52, storage unit 54 and communication interface 55.
The processing unit 52 includes a program information conversion processing module 53 and a pen input analysis unit 56. The storage unit 54 stores the data 50, user data and log data for program information conversion. The communication interface 55 communicates with the video recorder via the network 5.
Next, referring to FIG. 10 and FIG. 11, an outline of the processing performed by this system will be described.
FIG. 10 is a flow diagram of a television program guide issue procedure in this system. The processing shown in FIG. 10 is processing executed by the server 51 of the program information center 4.
First, when processing starts (121), the server 51 synchronizes with a server (e.g., EPG server) which is the source of the program information obtained via the network 5, and acquires program information (122). Based on the acquired program information, the program information conversion data 50 to associate a position in the program schedule 40- with program information is created (123). This program information conversion data 50 can be created by for example the aforesaid procedure described in FIG. 5.
The server 51 then stores the program information conversion data 50 (124), and prints it as a television program guide (125). The printed television program guide may be sold in bookstores together with ordinary program guide magazines, or distributed to users as a flier in newspapers.
FIG. 11 is a flow diagram of the recording reservation procedure after the television program guide of the first embodiment has been distributed to users.
The recording reservation processing of the first embodiment may be broadly divided into processing 130 by the user, processing 140 by the video recorder and processing 150 by the server.
The user 1 peruses the television program guide 41 in the user's home 2 or another location 3 (132), and selects the programs in which he is interested using the digital pen 10 (133). This program selection may employ the aforesaid method in FIG. 3 and FIG. 4.
When selection of the required programs by the user 1 is complete, the digital pen 10 is connected with the video recorder 21 by a means such as Bluetooth, and information acquired by the digital pen is forwarded to the video recorder 21 (135).
When the video recorder 21 receives the information from the pen (144), the server which is the connection destination is firstly determined by communication with the PLS server 65. Subsequently, information acquired by the digital pen 10 is transmitted to the determined server (the server 51 placed in the program information center 4) via the network 5 (145).
The server 51 receives information acquired by the digital pen 10 (154), analyzes digital pen trace data (155), converts pen gestures into commands if required, and acquires corresponding program information (156). The processing sequence of this server 51 may be the aforesaid processing of FIG. 6. Subsequently, the server 51 transmits the acquired program information to the video recorder 21 (157).
When the program information is received from the server 51 (146), the video recorder 21 completes the recording reservation based on the received program information (147). The processing result is output via the video display unit 27, and presented to the user 1 by the video display apparatus 30 (148).
Subsequently, when the user 1 confirms the processing result (136), the processing sequence is terminated (137).

SECOND EMBODIMENT

Referring to FIG. 12- FIG. 15, a second embodiment of this invention will now be described.
In the second embodiment, program data is downloaded to the video recorder beforehand, so there is no need to access the server of the program information center every time recordings are reserved or viewing programs are selected. Also, in the video recorder, a customized program schedule according to each user's preference and a recorded program list, can be output.
In the second embodiment, the same symbols are assigned to the same constructional elements as in the aforesaid first embodiment, and their detailed description is therefore omitted.
FIG. 12 is a system configuration diagram of the second embodiment.
The system of the second embodiment comprises a digital pen 10, a video recorder 21 corresponding to this system, an video display apparatus 30 such as a television or monitor, a storage device for storing the program information conversion data 50 connected to the video recorder 21, a printer 29, and a television program schedule 42 printed by the printer 29.
The program information conversion data 50 may be built into the video recorder 21 and kept in the home 2 of the user 1. Alternatively, it may be kept outside the home 2 and accessed via the network 5.
The printer 29 may be built into the video recorder 21, or externally connected to the video recorder 21. The video recorder 21 need not be a stand-alone product, but may be a personal computer connected to a tuner and connected to a recording medium (e.g., a hard disk drive and DVD disk drive).
Next, the processing of the service provided in the second embodiment will be described.
(A) The video recorder 21 acquires program information from a server (e.g., EPG server) which is the source of the program information via the network 5, and associates programs with the program information.
(B) The video recorder 21 prints a position detecting mark of the digital pen 10 and program schedule on a blank paper 45 by the printer 29 (162). The program schedule may also be printed on paper on which the position detecting mark has already been printed.
(C) The user 1 selects a program by marking it on the printed program schedule 42 using the digital pen 10. This program selection may be made by a method identical to that of the aforesaid first embodiment (FIG. 3 and FIG. 4).
(D) In the program selection operation, data acquired by the digital pen is stored in the digital pen 10, and forwarded to the video recorder 21 corresponding to this system with a suitable timing (164).
(E) The video recorder 21 analyzes the data acquired by the digital pen 10 (165), and converts the data acquired by the digital pen 10 into corresponding program information referring to the program information conversion data 50. Also, if required, pen gestures are converted into commands referring to the data 334 for pen gestures/commands.
(F) The video recorder 21 reserves the recording based on the obtained program information (166).
According to the second embodiment, since the user prints the program schedule, the latest program information can be acquired at any time. In addition, a customized program schedule according to user preferences can be made, so a program schedule which is easy to read and easy to select can be created. For example, a program in which a favorite actor appears can be printed out on the program schedule. The program schedule can be printed such that programs it is desired not to miss have been preselected. Conversely, the program schedule can be printed without printing genres and channel information which it is desired to avoid.
When the same video recorder is used by plural persons, by printing program schedules and selecting programs according to individual preferences, it is possible to identify who has reserved which programs, which is useful for looking up and retrieving recorded programs. To print program schedules according to individual preferences, user preferences and user histories can be stored in the database 54, different programs extracted for each user, and the program information conversion data 50 created for each user.
FIG. 13 is a flow diagram of the program schedule creation procedure of the second embodiment.
When the user 1 starts program schedule creation (172), the program data is installed in the video recorder 21 via the network 5 (185), and presents a program schedule customizing screen (186). The user 1 customizes the program schedule by using the displayed program schedule customizing screen (173), and transmits customization information to the video recorder (174).
The video recorder 21 creates the program schedule 42 and program information conversion data 50 based on the received customization information (187). This program schedule 42 and program information conversion data 50 can be created for example by an identical method to that of the first embodiment (FIG. 5). The created program information is stored (188), and the program schedule is printed on the paper 45 based on the created program information (189).
The user 1 obtains the printed program schedule 42 (175), and continues to perform program reservation processes. However, customized processing (186, 173, 174) is not indispensable to this system, and an ordinary usual program schedule which is not customized may also be printed.
FIG. 14 is a flow diagram of the recording reservation process according to the second embodiment.
The recording reservation process of the second embodiment is almost identical to that of the first embodiment shown in FIG. 11, but the step for conversion to program information on the video recorder 21 side is different. The program information conversion data 50, which is created in the program schedule generation procedure shown in FIG. 13, can also be transmitted to the server, and program information conversion performed by the server.
FIG. 15 is an example of a screen for program schedule customization displayed in step 173 of the program schedule creation procedure of the second embodiment.
A screen 90 for program schedule customization is output via the video display unit 27, and displayed on a display apparatus such as a television or the monitor of a personal computer.
The screen 90 for program schedule customization includes a column 91 where the user sets fields in which he is interested, and a column 92 where the user sets fields in which he is not interested. The content set by these procedures is saved in a memory 22 of the video recorder 21 as user data 54. The saved user data can be modified by edit buttons 93 and 94.
The screen 90 for program schedule customization includes a column 95 where the date (range) for printing the program schedule is set. By specifying this date column 95, today's program schedule, tomorrow's program schedule and one week of program schedules can be selected for printing. When an execution button 96 is pushed, print is executed. Programs in fields marked as interesting which were set in column 91, can be printed to stand out. Also, programs in fields marked as uninteresting which were set in column 92, can be excluded from the print-out.

THIRD EMBODIMENT

Next, referring to FIG. 16 and FIG. 17, a third embodiment of the present invention will be described. FIG. 16 is a system configuration diagram of the third embodiment of the present invention.
In the system of the third embodiment, as in the first embodiment, it is assumed that the program schedule is supplied from outside, but instead of-distributing it in the form of a magazine, it is distributed as a card or flier advertising the programs. Of course, it can also be distributed as a supplement to a magazine.
In the third embodiment, the same symbols are assigned to the same constructional elements as in the aforesaid first and second embodiments, and their detailed description is therefore omitted.
FIG. 17 shows an example of a program advertising card according to the third embodiment.
This card 300 contains program information 301, for example outline, actors and broadcasting time, a column 302 which sets the reservation specification method, a member registration column 303, a link column 304 and a mail column 305. The reservation specification method setting column 302 permits selection of whether the recording of the first episode is to be reserved, or whether all episodes from first to last are to be reserved together simply by checking the card. The storage destination of the program can also be specified, or creation of a series of DVD can also be set.
The member registration column 303 is a column where member registration in the nature of a program fan club can be performed. If a server 451 gathers logs of which programs were recorded, a service can be provided to send presents to viewers who have seen all episodes. In this way, audience rating can be improved. Moreover, program producers and sponsors can understand the viewer layer, easily collect opinions from viewers and-do interactive program-making.
